Y MURPHY COMPANY, O'FNEW PENNSYLVANIA -originai Y.ftppiieahmn med september 17., 1930, serial No. 482,422. Invia August 20, 1931. Serial No. 558,191.:

This invention relates to metal rcarlines for car roofs, especially car roofs ofthe kind wherein the roof sheets are movably mounted on the structure that supports them. The

f" principal objects of the invention are to devise a carline of relatively shallow depth withoutsacritice of strength or headroom; to adapt the carline for mo'vablysupporting the roof sheets along the side margins therei of; and also to adapt the carline for movably supporting the roof sheets both along the side margins thereof and along lines spaced inwardly of the sheets from said side margins.

The invention consists principally in a carline of hollow box section with the side margins of the lower section extended outwardly beyond the box and offset upwardly to form' seats for supporting the bodies of the roof L W sheets. It also consists in osetting the lower portions ofthe sides of the box outwardly with relation to the upper-portions thereof to form seats for the marginal portions of the room sheets. It also consists in the combinations and details hereinafter described.

' In the accompanying drawings which form part of this specification and wherein like numerals refer to like parts wherever they occur.

Fig. 1 is a plan view of a carline embodying my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is an enlarged side elevation of the end portion of said carline;

F ig. 4 is a cross-section of said carline on the line 4 4 of Fig. 3;

5 is an end view of said carline; and

Fig. 6 is a cross-section illustrating a modilied form of construction.

The present carline is of hollow box section i throughout its length. It comprises an upper member 11 of inverted channel section with outwardly extending flanges 12 at its lowerV margins, and a lower member 13 in the form of a fiat plate considerably wider than the upper member and riveted tiatwise to the flanges of the upper member and with its side margins odset upwardly beyond the edges of said flanges to form relatively wide seats 1'4 for the roof sheets.

The carline is preferablyL pitched and of creased.

KENSINGTON, `PENNSYLVANIA, A vCORPORJXCJON' OF CARLINE i end'aud this application led substantially uniforn'rdepth throughout the 'height than the body portion thereof. The

portion of the top of the carline that constitutes a seat 15 for the seam cap has a bolt hole 16 therethrough; and opposite such bolt hole the Vlower member of the carline is provided with an upwardly flanged hole 17 of sullicient size to Vpermit access toy said bolt hole from below. The carline hereinbefore described is `especially adapted for use with movably mounted roof sheets, as is more particularly shown and described in Inycopending appli'- cation Serial No. 482,422 filed September 17, 1980, of which the present application is a division. 1 Among the advantages'of the carline hereinbefre described is its great strength arising from its box sectionand the maintenance j of that section throughout the length ftherei ofi Another advantage is that,A for equal strength, it requires less depthv at the ridge than carlines of usual designs, in consequence of which the headroom of the car maybe increasedlor'theheight of the roof may be delThe ymodificationillustrating in Fig: 6 'is characterized'by forming seats 18 in theV sides of thebox portion of the carline additional to the seats 14 formed bythe upward offset- Y .ting of the bottommember ofthe carline. 'For this purpose', the lower .portion of the sides of thesheets are offset outwardly with'respect `tothe upper portions of thesides,1t hus forming ledges which extend the full length ofthe carline and constitute seats 18 for the margins of the sheets. f These ledges slope -outwardly `and downwardly and areat a slightly higher elevation than the seats 14 formed by the tlanges of the lower member.v This design of carline vis intended. for use with movably mounted roof sheetsand is especially useful when ridge pol-es and purlins are dispensed With. v-In'such case, the carlines are'made relatively Wide so as to spread its sheet support ing flanges a considerable distance apart, whereby the span between the sheet supports of adjacent carlines is considerably reduced without changing the distance between the center lines of the carlines. In such case, the seats formed by the upwardly offset flanges of the lower member of the carline support the body portions of the sheets, while the upwardly inclined marginal portions of the sheets are supported by the seats formed by offsetting the sides of the body of the carline.

For further illustration and description of a ear roof embodying said modified form of carline reference is made to applicants copending application Serial No. 509,640 filed J anuary 19, 1931.

That I claim is:

1. A carline comprising an upper member of inverted channel shape with lateral flanges and a lower plate-like member secured to said flanges, said lower member being wider than said upper member and having its side man gins raised.

2. A carline of box girder type comprising an upper member of inverted channel shape throughout its length and a lower plate-like member secured thereto throughout the length thereof, said lower member having its side margins formed into panels that are raised above the bottom of the upper member said members having vertically alined hol-es and the edge of the lower hole being winged up.

3. A carline of box girder type comprising an upper member of inverted channel shape throughout its length and a lower plate-like member secured thereto throughout the length thereof, said lower member having its side margins formed into panels that'are raised above the bottom of the upper member.

4. A carline of box girder type comprising an upper member of inverted channel shape throughout its length and a lower plate-like member secured thereto through the length thereof, said lower member having its side margins formed into panels that are raised above the bottom of the upper member. the depth of said carline decreasing from ridge to eaves.

5. A carline having sheet supporting ledges in the sides thereof and additional sheet supports outwardly beyond said sides and at a somewhat low-er level than said. ledges.

6. A carline comprising an upper member of inverted channel-shaped cross-section with outstanding base flanges and a lower platelike member secured to said flanges, said lower member being wider than said upper member and having its side margins raised to form supports for roof sheets, the lower portions of the sides of said upper member being offset outwardly with relation to said upper portions to form ledges for supporting said roof sheets, said ledges being somewhat higher than said marginal supports.

T. A carline comprising a metal member having its side margins raised to form roof sheet supporting flanges and having the lower portions of its body portion offset outwardly with relation to the upper portions thereof to provide other roof sheet supports that incline downwardly and outwardly and are located somewhathigher than said side marginal supports.

S. A boxlike carline comprising an upper member of inverted channel-shaped cross-section with ther lower portions of its sides offset outwardly with relation to the upper portions thereof to form ledges for supporting roof sheets and with outstanding base flanges and a lower plate-like member secured to said flanges, said ,lower member being wider than said upper member and having its side margins raised to form supports fo-r roof sheets, the inverted channel of said upper member being narrower at the top than at the bottom of said member and having its side offset to form ledges for supporting roof sheets.

9. A boxlilre carline comprising an upper member of inverted channelshaped cross-section with the lower portions of its sides offset outwardly with relation to the upper portions thereof tov form ledges for supporting roof sheets and with outstanding base flanges and a lower plate-like member secured to said flanges, said lower member being wider than said upper member and having its side margins raised to form supports for roof sheets,

said ledges being inclined downwardly and loutwardly crosswiseof said carline and being somewhat higher than said raised side margins.
